    The documentation of the use of this installation script is available here.

  • Getting the frame pkt_pts from ffmpeg

    2 février 2018, par kama

    I record a stream similar to this (but I pipe the image to stdout and process the frames in real time) :

    ffmpeg -debug_ts -y -i http://my_stream.com -strict -2 out.mp4

    Now I need to map my frames to the pkt_pts. This pkt_pts I can get by running :

    ffprobe -i http://my_stream.com -show_frames -select_streams v:0

    Although starting ffprobe is not an option since I need to excactly know which pkt_pts belongs to what frame.
    Therefore I’m using the -debug_ts in my ffmpeg call, which gives me a lot of output to stderr, which I then parse out. The only output line which matches the number of frames is the one which starts with : muxer <- type:video This line does contain a pkt_pts, but it always starts with 0 (not the global pkt_pts).

    Is there a way to map a frame, to the global pkt_pts in real time with ffmpeg ?
